[0046] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0047] Example 1

[0048] like Figure 1-6 As shown, a glue filling device provided according to the present invention includes a clamping component 1, a circulating hose 2 and a glue filling mechanism 3; a clamping block 101 is provided on the top of the clamping component 1, and a hose positioning seat 103 is provided at the bottom of the clamping component 1, and the clamping block 101 and the hose positioning seat 103 cooperate to fix the circulating hose 2; the circulating hose 2 includes a hose fixing seat 203 and a hose with an accommodating cavity, and a circulation channel is provided inside the hose fixing seat 203, and the circulation channel is connected to the accommodating cavity; the glue filling mechanism 3 is plugged into and matched with the hose fixing seat 203, and a glue filling channel is provided inside the glue filling mechanism 3, and the output end of the glue filling channel is connected to the circulation channel; the glue filling mechanism 3 is tightly connected to the clamping component 1.

[0049] The present invention utilizes a compression assembly 1 to compress and secure a circulating hose 2, which is then precisely filled with glue by a glue filling mechanism 3. This process is leak-free, preventing the glue from solidifying upon contact with air, and is convenient and simple to maintain. The circulating hose 2 is reusable, reducing the use of disposable hoses, significantly reducing plastic waste containing chemical components each year, and minimizing environmental damage.

[0050] like Figure 7 and 8 As shown, the glue filling mechanism 3 includes a glue feed block 301, which is plugged into the hose holder 203. The outer wall of the glue feed block 301 is arranged to fit the inner wall of the circulation channel of the circulating hose 2. The glue feed block 301 is provided with an outer edge on the side away from the hose holder 203. The outer edge can seal the circulation channel of the circulating hose 2, preventing glue from overflowing and isolating the glue from air, thereby achieving a recycling effect.

[0051] The glue filling mechanism 3 includes a glue filling component and a glue feeding component, and the glue filling component and the glue feeding component are plugged in and matched; the glue filling component includes a telescopic rod 304, a glue filling head 303 and a glue filling block 302 which are sequentially sleeved from the inside to the outside; the glue feeding component includes a limiting rod 312, a sliding ring 313 and a glue feeding block 301 which are sequentially sleeved from the inside to the outside, and the side of the limiting rod 312 away from the glue filling component is fastened to the glue feeding block 301; the side of the limiting rod 312 close to the glue filling component is snap-fitted with the sliding ring 313, and the side of the glue feeding block 301 close to the glue filling component is sealed; the glue filling head 303 and the glue feeding block 301 are plugged in and matched The glue filling head 303 and the sliding ring 313 are connected in transmission, and the limit rod 312 is connected in transmission with the telescopic rod 304; a first glue filling channel is provided inside the glue filling block 302, and a second glue filling channel is provided inside the glue filling head 303, and the output end of the first glue filling channel is connected to the input end of the second glue filling channel; a third glue filling channel is provided inside the glue feeding block 301, and the third glue filling channel is respectively connected to the glue filling head glue outlet 319 of the second glue filling channel and the external environment; the glue filling head glue outlet 319 is provided on the inner side of the glue filling head 303, and the telescopic rod 304 can seal the glue filling head glue outlet 319.

[0052] The glue filling mechanism 3 also includes a locking nut 305, a first flood seal 306, a first spring 307, a first sealing ring 309, a second sealing ring 311, a second flood seal 314, a third flood seal 315, a second spring 316, a glue inlet 318, a glue inlet 320 of the glue feeding block, a quick clamp 321, a slider guide rail 322 and a transition block 323.

[0053] During glue filling, manually tighten the quick-action clamp 321, causing the glue filling block 302 and transition block 323 to move smoothly to the right on the slider guide 322, allowing the glue filling assembly to be inserted into the glue feed assembly. The insertion end of the glue filling head 303 is inserted into the glue feed block 301. The glue filling head 303 presses against the sliding ring 313 and moves rightward. The sliding ring 313 begins to compress the first spring 16. The second flood seal 314 cooperates with the limit rod 312 to form the glue feed block inlet 320, opening the third glue filling channel. During the insertion of the glue filling assembly into the glue feed assembly, the limit rod 312 remains stationary, pressing against the telescopic rod 304. As the glue filling head 303 moves rightward, the telescopic rod 304 compresses the first spring 307, causing relative movement of the telescopic rod 304 to the left. At this point, the glue filling head outlet 319 opens, connecting the second and third glue filling channels. Then open the glue inlet 318, and the glue enters the first glue filling channel from the glue inlet 318, then enters the second glue filling channel, enters the third glue filling channel from the glue filling head glue outlet 319, passes through the glue inlet 320 of the glue feeding block, and is output from the output end of the third glue filling channel to the circulation channel of the circulating hose 2.

[0054] After glue filling is complete, the glue filling assembly retracts, and the second spring 316 in the glue feed assembly pushes the sliding ring 313 to the left. The limit rod 312 engages with the sliding ring 313 and seals the glue feed block 301. The second flood seal 314, the limit rod 312, and the sliding ring 313 cooperate to seal the mating surface between the limit rod 312 and the sliding ring 313. The third flood seal 315, the sliding ring 313, and the glue feed block 301 cooperate to seal the mating surface between the sliding ring 313 and the glue feed block 301. At this point, the third glue filling channel is closed and sealed. In the glue filling assembly, the glue filling head 303 exits the glue feed block 301, and the first spring 307 pushes the telescopic rod 304 to the right. The telescopic rod 304 and the glue filling head 303 cooperate to seal, preventing glue from overflowing from the glue filling head outlet 319. The locking nut 305 presses the first flood seal 306 tightly to prevent glue from overflowing from the left end of the glue filling block 302 .

[0055] like Figure 9 and 10 As shown, the rubber hose of the circulation rubber hose 2 is made of aluminum alloy, which can withstand the corrosion of glue and the wear during use, thereby achieving the purpose of reuse.

[0056] The circulation channel of circulating hose 2 is provided with a connecting hole at the end thereof, through which the rubber tube of circulating hose 2 communicates with the circulation channel of circulating hose 2; the glue feed block 301 does not contact the connecting hole. A tail plug is provided inside the rubber tube of circulating hose 2. Glue enters the circulation channel inside the rubber tube holder 203. Once inside the rubber tube of circulating hose 2, the glue rises, driving the tail plug upward.

[0057] The bottom of the hose fixing base 203 is provided with a glue outlet 204, which is equipped with a matching sealing head 207. The sealing head 207 can seal the glue outlet 204 to prevent glue from overflowing and ensure that the glue in the circulating hose 2 is isolated from the air, achieving the effect of recycling. The hose positioning base 103 is provided with a groove that matches the sealing head 207, and the sealing head 207 is placed in the groove.

[0058] A compression block 101 is located at the top of the compression assembly 1, and a hose retaining seat 103 is located at the bottom. These two components work together to secure the circulating hose 2, preventing it from moving during the filling process. A sensor 107 is located at the top of the compression block 101. Once the circulating hose 2 is filled with glue, the sensor 107 signals the filling equipment that filling is complete.

[0059] The pressing assembly 1 includes a fixed base plate 110 , and the pressing assembly 1 is mounted on the base of the glue filling device through the fixed base plate 110 ; the glue filling mechanism 3 is fastened to the pressing assembly 1 through the fixed base plate 110 .

[0060] The pressing assembly 1 further includes a lifting cylinder 102, an emergency stop switch 104, a glue filling switch 105, a lifting control valve 106, a pneumatic control valve 108 and a receiving cup 109. The lifting cylinder 102 drives the pressing block to compress the circulating hose.

[0061] Move the lifting control valve 106 to raise the lifting cylinder 102 to the highest point, insert the circulating hose 2 and position it properly, then move the lifting control valve 106 to lower the lifting cylinder 102, and the pressing block 101 will compress the circulating hose 2. Manually move the glue filling mechanism 3, insert the glue filling mechanism 3 into the circulating hose 2 and lock it. Press the glue filling switch 105 to start the glue filling equipment. The glue flows through the pipeline, passes through the pneumatic control valve 108, enters the glue filling channel of the glue filling 3, and then enters the circulation channel of the circulating hose 2. It enters the hose of the circulating hose 2 through the connecting hole. The glue in the circulating hose 2 rises, driving the tail plug inside the hose to move upward. When the tail plug reaches the highest point, the sensor 107 senses it and stops the glue filling equipment from running, stopping glue filling.

[0062] This application uses PLC precise control, which can effectively improve the filling accuracy. By manually controlling the rise and fall of the clamping component 2, the circulating hose 2 is ensured to be securely fixed during the filling process. The circulating hose 2 is filled with glue through the filling mechanism 3, and there will be no glue leakage during filling. After the filling is completed, there is no glue dripping from the circulating hose 2 and the filling mechanism 3. The circulating hose 2 and the filling mechanism 3 adopt a self-resetting structure to solve the problem of glue overflow and achieve a sealing effect. While ensuring customer use, the use of disposable hoses is reduced, achieving the effect of protecting the environment.

[0063] Example 2

[0064] Based on Example 1, the circulating hose 2 includes a first rubber-filled hose 201 and a second rubber-filled hose 202. The circulation channel of the circulating hose 2 includes a first channel 205 and a second channel 206. The first rubber-filled hose 201 communicates with the first channel 205, and the second rubber-filled hose 202 communicates with the second channel 206. The hose's thickness can be adjusted based on the glue ratio to cover a wide range of usage scenarios.

[0065] Furthermore, the two sensors 107 are respectively provided corresponding to the first rubber filling tube 201 and the second rubber filling tube 202 .

[0066] Two glue filling mechanisms 3 are symmetrically arranged on both sides of the pressing assembly 1. The glue filling channel of one glue filling mechanism 3 is connected to the first channel 205, and the glue filling channel of the other glue filling mechanism 3 is connected to the second channel 206. The two glue filling mechanisms 3 can be used simultaneously or separately, which greatly improves work efficiency.

[0067] How it works

[0068] Move the lifting control valve 106 to raise the lifting cylinder 102 to the highest point, insert the circulating hose 2 and position it properly, then move the lifting control valve 106 to lower the lifting cylinder 102, and the pressing block 101 will compress the circulating hose 2. Manually move the glue filling mechanism 3, insert the glue filling mechanism 3 into the circulating hose 2 and lock it. Press the glue filling switch 105 to start the glue filling equipment. The glue flows through the pipeline, passes through the pneumatic control valve 108, enters the glue filling channel of the glue filling 3, and then enters the circulation channel of the circulating hose 2. It enters the hose of the circulating hose 2 through the connecting hole. The glue in the circulating hose 2 rises, driving the tail plug inside the hose to move upward. When the tail plug reaches the highest point, the sensor 107 senses it and stops the glue filling equipment from running, stopping glue filling.
